What Are Interior Doors?

The gems in your home, hidden from the outside world!

Interior doors are more than just a functional element in your house; they contribute to the overall aesthetic and privacy of your living space. As an experienced interior door installer, we’ve seen how the right door can transform a room. When we talk about interior doors, we’re referring to the doors that connect rooms inside your home, as opposed to exterior doors that serve as the main entry points.

Unlike exterior doors, they don’t add to your curb appeal, and interior doors are usually lighter and may not be weatherproof, but they play a crucial role in defining spaces within your home.

Types of Interior Doors

Not all interior doors are the same, and understanding the different types of interior doors is key to choosing the right one for your space.

Each type of door, from sliding doors to traditional swinging doors, offers unique benefits and aesthetic appeal.

Whether you replace existing doors or install new doors, it’s important to consider how the door’s functionality aligns with your home’s layout and your personal style.


What Are the Different Styles of Interior Doors?

Hollow Core

Hollow core doors are a popular and cost-effective choice for most interior doors. These doors are lightweight and easily installed, making them a great option for interior door replacement for bedroom doors and closet doors. Despite their name, they aren’t completely hollow; they contain a honeycomb-like structure inside, which provides some level of sound insulation and strength.

Solid Core

Solid core doors, as the name suggests, are made from solid door materials, offering more durability and soundproofing than hollow core doors. Ideal for areas where privacy is paramount, such as bedrooms or home offices, these doors are heavier, more secure, and provide a sense of solidity and quality. You typically see these used as an entry door connecting the inside of a garage to the inside of the home.

What Materials Are Used for Interior Doors?


Wood is a classic choice for interior doors, known for its natural beauty and versatility. Whether you’re looking for traditional or modern designs, wooden doors can be crafted to suit any interior style. Their natural grain patterns bring warmth and character to any room.


Fiberglass doors are a durable and low-maintenance option. These doors resist warping, denting, and cracking, making them a practical choice for areas with high usage. Fiberglass can be designed to mimic the look of wood, providing the aesthetic appeal of wood without the maintenance.


Vinyl doors are known for their durability and ease of maintenance. They are resistant to moisture, making them a suitable choice for areas like bathrooms or basements. Vinyl doors come in a variety of finishes and can be a cost-effective option for interior door replacement. You typically see this material for interior sliding glass doors, a rare but wonderful choice.

Selection and Design of Interior Doors

How to Choose the Right Interior Door?

Great question! Choosing the right interior door involves considering both the door’s function and its impact on your home’s aesthetics. When selecting a new door, think about the space it will occupy – is it a high-traffic area, does it require privacy, or is it more about creating an open feel? Also, consider the door’s alignment with the overall design theme of your home.

What Are the Current Design Trends in Interior Doors?

Current design trends in interior doors include minimalist designs, sleek trim, the use of bold colors, and incorporating complete glass panels for a more open and airy feel. Barn doors and sliding bypass doors are gaining popularity for their space-saving and stylish appearance, especially in smaller rooms or where a swinging door might be impractical. Contact your door consultant for recommendations based on the room where the door will be placed.


What Customization Options Are Available for Interior Doors?

Want to incorporate your personality inside of your home? Customization options for interior doors are vast. From the type of door – be it a classic swinging door, a space-saving sliding door, or elegant French doors – to the choice of materials, colors, and hardware, there are endless ways to make your new interior doors unique. You can also choose between a prehung door or slab door options depending on whether you’re replacing old doors or installing a door in a new door frame.

Technical Aspects of Interior Doors

What Are the Standard Dimensions of Interior Doors?

The standard dimensions of most interior doors typically range from 24 to 36 inches in width and 80 to 96 inches in height. However, these dimensions can vary depending on the specific application and the structure of the building. It’s important to measure the door frame accurately before selecting a new door.


How Do Interior Doors Contribute to Soundproofing?

Fantastic question! Interior doors contribute significantly to soundproofing in a home. Solid doors, for instance, offer better sound insulation compared to hollow core doors. The door’s material and its core also play a crucial role in its soundproofing capabilities. Proper installation and the use of additional soundproofing materials can further enhance this feature.

Do Interior Doors Affect Insulation and Energy Efficiency?

While interior doors are not as crucial as exterior doors in terms of insulation and energy efficiency, they still contribute to maintaining a consistent temperature in different rooms. Doors with solid cores offer better insulation compared to hollow core doors. Additionally, the correct installation of doors ensures there are no gaps that might lead to energy loss.

Installation and Maintenance of Interior Doors


Should You Install Interior Doors Yourself or Hire a Professional?

It’s always recommended to hire a professional (unless you’re a door professional yourself), because incorrect interior door installation can cost you precious time, money, and sometimes it could feel like it costs you your sanity! It’s not easy to install a door that perfectly operates, just like it’s probably not easy to do the profession that you’re skilled in, so we always recommend leaving the door work to the professionals!

A trained professional can swap a door in just a few hours, or at least less than one day!

How to Maintain Different Types of Interior Doors?

Maintenance Tips for Wooden Doors

Wooden doors require regular dusting and occasional polishing to maintain their appearance. Protect them from moisture to prevent warping and apply a fresh coat of paint or varnish every few years to keep them looking new and in good shape, though most of the time this isn’t necessary since they are far from the outside elements.

Maintenance Tips for Fiberglass Doors

Fiberglass doors are low maintenance. They can be cleaned with mild soap and water. Inspect the seal and weather stripping periodically, they may need to be replaced if necessary to ensure the doors remain energy efficient.


Maintenance Tips for Glass Doors

Glass doors, often used as patio doors or office partitions, require regular cleaning with a glass cleaner to keep them spotless and clear. Check the frames and hinges regularly for any signs of wear and address them promptly.

Maintenance Tips for Medium Density Fiberboard Doors

Medium Density Fiberboard (MDF) doors are known for their durability. Regular cleaning with a damp cloth and mild detergent will keep them looking fresh. Avoid excessive moisture exposure to prevent swelling or warping. They make a great interior door because they are away from the outside elements, but a terrible exterior door, as a little bit of water inside will wreak havoc.

What Are Common Issues with Interior Doors and Their Solutions?

Common issues with interior doors include sticking, squeaking hinges, or even a misaligned strike plate. These can often be fixed with simple adjustments, such as lubricating hinges, tightening screws, or sanding down areas where the door sticks. For more significant issues, like a warped door, it may be necessary to replace the old door.

Safety and Regulations for Interior Doors


What Safety Standards Apply to Interior Doors?

Safety standards for interior doors include fire ratings, especially for doors leading to attached garages or utility rooms. It’s also important to ensure doors are easy to open and do not pose a hazard in emergency situations. Using doors with safety glass, particularly for interior French doors, is another crucial aspect of safety.

What Building Codes and Compliance Issues Are Relevant to Interior Doors?

Building codes for interior doors focus on dimensions, fire safety, and accessibility. Compliance with the Americans with Disabilities Act (ADA) is essential for public buildings and advisable in homes to cater to accessibility needs. Local building codes may also dictate certain requirements based on the geographical location and specific use of the doors.

Additional Considerations for Choosing Interior Doors


How Do Interior Doors Cater to Accessibility Needs?

Interior doors that cater to accessibility needs feature:

  • wider openings
  • lower thresholds
  • and lever-style handles for ease of use by individuals with mobility challenges.

Pocket doors or barn doors can be excellent choices for saving space and reducing the physical effort needed to open and close doors.

What Is the Environmental Impact of Different Door Materials?

The environmental impact of different door materials varies.

  • Wood, while natural, may raise concerns about deforestation unless it’s sourced sustainably.
  • Fiberglass and vinyl offer durability and longevity but are not biodegradable.

Choosing eco-friendly materials and considering the entire lifecycle of the door are important factors in reducing environmental impact.


What Factors Affect the Cost of Interior Doors?

The cost of interior doors is influenced by several factors including the material, style, size, and any custom features. Solid doors tend to be more expensive than hollow core doors, and custom sizes or designs, such as sliding bypass doors or intricate glasswork, also add to the cost.

Installation service, especially for complex door types like a pre hung door or replacing an existing door, will also be a factor in the overall cost.

Frequently Asked Questions about Interior Doors

We’re probably the only weirdos out there who obsess over doors, so we understand that you might have numerous questions about interior doors, from maintenance to installation processes. At Your New Door, we’re not just experts in doors; we’re also here to provide all the answers you need.

  • What are the best interior doors?

    The best interior doors depend on your specific needs. Solid wood doors are excellent for durability and sound insulation, featuring a classic, timeless appeal. For a more budget-friendly option, MDF (Medium Density Fiberboard) doors are ideal; they provide a smooth finish, resist warping, and maintain an attractive appearance. In humid climates, fiberglass doors are advantageous due to their resistance to moisture and minimal warping, making them a practical choice for maintaining long-term door integrity.

  • What is the most popular style of interior doors?

    The most popular style of interior doors is Scandinavian design, celebrated for its minimalist approach and emphasis on simplicity and geometric shapes. This style features doors with clean, straight lines and light colors, devoid of any curved lines, moldings, or decorative elements. The Scandinavian design’s appeal lies in its ability to create a sense of spaciousness and calm, making it a favored choice for modern interiors.

  • Is it worth getting solid interior doors?

    Yes, investing in solid core interior doors is worthwhile, especially for areas where privacy and sound insulation are priorities. These doors, made from a dense core material, are heavier and more effective at blocking noise than their hollow counterparts. They’re particularly suitable for bedrooms, bathrooms, and home offices, offering both enhanced privacy and a premium feel.

  • What is a timeless interior door?

    A timeless interior door design is the Shaker door. Known for its skilled craftsmanship and simplicity, the Shaker door features a flat, recessed panel framed by a thick, sturdy border. Its clean and straightforward aesthetic ensures it remains relevant and stylish, regardless of changing trends or tastes. This makes Shaker doors a perennial favorite in homes, appreciated for their classic look and adaptability to various interior styles.

  • How do you tell if a door is solid or hollow?

    To determine if a door is solid or hollow, you can perform a simple sound test. Knock on the door and listen to the sound it produces. If the knock results in a dull thud, the door is likely solid core. However, if you hear a hollow echo, the door is most likely hollow core. This method is quick and effective for identifying the door’s construction without needing to examine its internal structure.

  • What is the latest trend for interior doors?

    The latest trend in interior doors is the increasing popularity of sliding glass doors. These doors are highly sought after in contemporary homes, especially those with open-floor plans. They offer a sleek, modern look while also serving a practical function by delineating spaces without obstructing light or views. Sliding glass doors are particularly beneficial in smaller rooms or areas where space is at a premium, as they do not require the swing space traditional doors need.

  • How much is an interior door?

    The cost of an interior door varies widely, typically ranging from $150 to $2,500, with an average cost of around $786. This price variation depends on several factors including the type of door, the materials used, the complexity of the design, and the hardware selected. Whether you opt for a basic hollow core door or a high-end solid wood model will significantly influence the overall cost.

  • Can I replace an interior door without replacing the frame?

    Yes, you can replace an interior door without replacing the frame if the frame is still in good condition and the new door is the same size as the old one. This approach can save time and reduce costs. It’s important, though, to check the frame for any signs of damage or wear, such as cracks, rot, or warping, which might necessitate a frame replacement to ensure the new door functions properly and securely.
